IMPROVEMENT IN ROLLER AND HARROW COMBINED.

To all whom it may concern:

Be it known that I, WILLIAM R. MEARS, of the city of Grafton, in the county of Jersey and State. of Illinois, have invented a new and useful Improvement in Combined Roller and Harrow for Agricultural Purposes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanyingdrawings, and to the letters of reference marked thereon, in which Figure l is a side elevation of one of the improved machines. Fig. 2 is a sectional rearend view of the machine with the rollers re moved, in which condition the machine only acts as a barrow. Fig. 3 is a top plan of the machine with the rollers and barrows combined.

I construct the wrought-iron frame A, having the tongue a for the attachment of the propelling-power and connected with the axle B, on which the roller 0 revolves.

To the tongue at are secured the barrows D.

The frame A, in its vertical arm supporting one end of the axle B, is jointed at b, the joint being made good by a stirrup-strap, c, which surrounds the jointed parts when they curve, so that these jointed parts are firmly secured against movement in any direction whatever.

The stirrup is secured by means of screwbolts.

WVhen thejoint b is unfastened and the nut 1!. taken off the roller 0, or any part ofit, can be slid off from the axle-shaft B.

The roller 0 is made of cast-iron, stone, or

wood, and is in four parts, d, e,f, and g. The' parts of the roller remaining are d and g, which then act and are meant to be used as common wheels. The machine is then a harrow.

The barrows are supported from the frame by means of the arms 70 on the books 1', and they can be easily lifted out of these books. The barrows are formed of teeth set into a single straight bar, the teeth in each harrow beingset so as to cover the centers ot'the spaces left by the other barrows. The barrows are further supported and regulated by the hanging arms I, which are attached to and moved by means of the levers m, so that they can be raised from the ground to pass obstacles or be out of way when not used. The levers m are pivoted to the t'ulcrums m, which are erected upon the shaft to. The manner of securing these parts is by screw-bolts, so that all of them can be removed at will. When the levers m are unfastened and the arms is of the harrows D are lifted out of the hooks the barrows can be removed from the machine entirely, and it then can be used as a simple roller.

The roller-wheels d and g-fit up against a shoulder in the axle B, and they are secured in position by the nuts 12 on the outer ends of the axle.

At a convenient point on the frame A there should be constructed the riders seat S.

Having described my invention, whatI claim and desire to secure by Letters Patent, is

1. The combination and arrangement of the levers m m, connecting-bars l l, and stay-bars It It with the barrow-bars D D and frame A of my improved machine, all substantially in the manner and for the purpose herein described.

2. The arrangement and combination, with each other and with the frame A, of the sec tional rollers U G and barrows D D, to constitute a combined roller and harrow, substantially as herein described.
